Description

Technical Field

[0001] This application relates to the field of aerosol atomization technology, specifically to a liquid guiding component, an atomizing core assembly, and an atomizing device. Background Technology

[0002] Electronic atomization devices can be used to atomize aerosol matrices. Typically, these devices contain a liquid guide that adsorbs the aerosol matrix. After adsorbing the matrix, the guide provides heat to a heating element to generate the aerosol. However, in existing technologies, the cylindrical structure of the liquid guide inevitably leads to internal compression and external stretching issues. This causes changes in the flow channels within the guide, compromising its liquid guiding performance and resulting in leakage or poor liquid flow, negatively impacting the user experience. Utility Model Content

[0003] This application provides a liquid guiding component, an atomizing core assembly, and an atomizing device, aiming to solve the technical problem of poor liquid guiding performance of existing liquid guiding components.

[0004] Some embodiments of this application provide a liquid guiding component, including at least two liquid guiding layers, wherein the at least two liquid guiding layers include an inner liquid guiding layer and an outer liquid guiding layer;

[0005] At least two of the liquid guiding layers have an unfolded state and a curled state. The inner liquid guiding layer is configured as an inner liquid guiding cylinder in the curled state, and the outer liquid guiding layer is configured as an outer liquid guiding cylinder that wraps around the outside of the inner liquid guiding cylinder in the curled state. The circumference of the outer liquid guiding cylinder is greater than the circumference of the inner liquid guiding cylinder.

[0006] When the ends of at least two of the liquid guiding layers are flush, in the unfolded state, a curling gap is formed between the inner liquid guiding layer and the outer liquid guiding layer, and in the curled state, the inner liquid guiding cylinder and the outer liquid guiding cylinder are in contact.

[0007] In some embodiments, at least two liquid-conducting layers further include an intermediate liquid-conducting layer disposed between the inner liquid-conducting layer and the outer liquid-conducting layer;

[0008] The intermediate liquid guiding layer is configured in the curled state as an intermediate liquid guiding cylinder wrapped between the inner liquid guiding cylinder and the outer liquid guiding cylinder, and the circumference of the inner liquid guiding cylinder, the intermediate liquid guiding cylinder and the outer liquid guiding cylinder increases sequentially.

[0009] In the unfolded state, the intermediate liquid guiding layer forms a curling gap with the inner liquid guiding layer and the outer liquid guiding layer respectively, and in the curled state, the intermediate liquid guiding cylinder is attached to the inner liquid guiding cylinder and the outer liquid guiding cylinder respectively.

[0010] In some embodiments, at least two of the liquid-conducting layers further include multiple intermediate liquid-conducting layers;

[0011] The circumference of the plurality of intermediate liquid guiding cylinders increases sequentially from the inner liquid guiding cylinder to the outer liquid guiding cylinder; in the unfolded state, the curling gap is formed between adjacent intermediate liquid guiding layers, and in the curled state, adjacent intermediate liquid guiding cylinders are in contact with each other.

[0012] In some embodiments, the liquid guiding element also has a retention portion;

[0013] In the unfolded state, the retention portion is disposed at at least one end of at least one layer of the liquid guiding layer; in the curled state, the retention portion extends along the side of the outer liquid guiding cylinder away from the inner liquid guiding cylinder.

[0014] In some embodiments, the retention portion is provided at both ends of each of the liquid guiding layers;

[0015] In the unfolded state, the retention portions at both ends of each liquid guiding layer are stacked and fixed to each other; in the curled state, the ends of the retention portions away from the outer liquid guiding cylinder are flush with each other.

[0016] In some embodiments, the liquid guiding layer has a length along the curling direction and a thickness along the curled radial direction;

[0017] The length of the liquid guiding layer increases sequentially from the inner liquid guiding layer to the outer liquid guiding layer, and the increase in length ΔL between adjacent liquid guiding layers is:

[0018] △L=L n+1 -L n =2(π-1)W n ;

[0019] Where n is a positive integer, L n W is the length of the nth liquid-conducting layer. n Let be the thickness of the nth liquid-conducting layer.

[0020] In some embodiments, each of the liquid-conducting layers has the same thickness.

[0021] In some embodiments, the liquid guiding layer is made of a flexible porous material.

[0022] Some embodiments of this application also provide an atomizing core assembly, including:

[0023] The liquid guiding element described in any of the above embodiments is used to adsorb aerosol matrix;

[0024] A heating element, in contact with the liquid guiding element, the heating element being used to atomize the aerosol matrix; and,

[0025] Atomizing tube, wherein the liquid guiding element and the heating element are installed in the atomizing tube.

[0026] Some embodiments of this application also provide an atomizing device, including:

[0027] The atomizing core assembly described in any of the above embodiments;

[0028] A power supply component, electrically connected to the atomizing core assembly, is used to supply power to the atomizing core assembly; and...

[0029] The housing is in which both the atomizing core assembly and the power supply assembly are mounted.

[0030] According to the liquid guiding component in the above embodiments, by setting the length of the outer liquid guiding layer to be greater than the length of the inner liquid guiding layer along the circumferential direction of the liquid guiding component, a curling gap can be formed between the inner and outer liquid guiding layers before the liquid guiding component is curled (i.e., in the unfolded state). This curling gap can be used to provide deformation space for the inner and outer liquid guiding layers during curling, thereby reducing the compressive force on the inner liquid guiding layer during curling and reducing the tensile force on the outer liquid guiding layer during curling. This reduces the deformation of the flow channels inside the inner and outer liquid guiding cylinders, making the liquid guiding component less prone to leakage or poor liquid guiding.

For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0044] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0045] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0046] This application provides an atomizing device, such as... Figure 1As shown, the atomizing device may include an atomizing core assembly 1, a power supply assembly 2, and a housing 3. The atomizing core assembly 1 and the power supply assembly 2 may be installed inside the housing 3. The power supply assembly 2 may be electrically connected to the atomizing core assembly 1 to supply power to the atomizing core assembly 1. The atomizing core assembly 1 may be used to atomize the aerosol matrix to generate aerosol.

[0047] Depending on the structure, shape, and arrangement of the atomizing core assembly 1 and the power supply assembly 2 within the housing 3, the housing 3 can be box-shaped, strip-shaped, or columnar, etc., and can also be configured with detachable upper and lower housings or detachable left and right housings. The power supply assembly 2 may include an electrically connected battery and a circuit board, and the atomizing core assembly 1 can be electrically connected to the circuit board, allowing the battery to provide power to the atomizing core assembly 1 through the circuit board. This application does not impose any special limitations on the specific structure of the power supply assembly 2 and the housing 3.

[0048] In addition, such as Figure 2 As shown, the atomizing core assembly 1 may include a liquid guiding component 10, a heating element 20, and an atomizing tube 30. The pins of the heating element 20 can be electrically connected to the circuit board of the power supply assembly 2, allowing the battery to power the heating element 20. The atomizing tube 30 is connected inside the housing 3, and the liquid guiding component 10 is in contact with the heating element 20 and disposed inside the atomizing tube 30. The heating element 20 may employ a heating wire or heating mesh structure, and the liquid guiding component 10 may be sleeved inside the atomizing tube 30 and wrapped around the outside of the heating element 20. Of course, in other embodiments, the heating element 20 may also wrap around the outside of the liquid guiding component 10. This application does not impose any special limitations on the specific structure of the atomizing core assembly 1.

[0049] When the atomizing device is working, the liquid guiding component 10 can adsorb the aerosol matrix stored in the housing 3, and the heating element 20 can heat the aerosol matrix adsorbed by the liquid guiding component 10 to atomize and generate aerosol. The heating element 20 is typically configured as a cylindrical structure. To increase the contact area between the liquid guiding component 10 and the heating element 20, such as... Figure 3 As shown, the liquid guiding component 10 is typically rolled into a cylindrical structure. However, when the cylindrical liquid guiding component 10 is rolled, as... Figure 4 As shown, the inner layer 10a of the liquid guiding component 10 is compressed, causing the flow channels in the inner layer 10a to deform axially along the cylindrical structure. Simultaneously, as... Figure 5 As shown, the outer layer 10b of the liquid guiding component 10 is stretched, causing the flow channels in the outer layer 10b to deform circumferentially along the cylindrical structure. This disrupts the flow channels inside the liquid guiding component 10, leading to leakage or poor liquid guiding in the atomizing device.

[0050] To address the aforementioned technical problems, this application also provides a liquid guiding component 10, such as... Figure 6 and Figure 7As shown, the liquid guiding component 10 may include at least two liquid guiding layers 11, which may include an inner liquid guiding layer 11a and an outer liquid guiding layer 11b. The at least two liquid guiding layers 11 have an unfolded state and a rolled state. In the rolled state, the inner liquid guiding layer 11a is configured as an inner liquid guiding cylinder 11A, and the outer liquid guiding layer 11b is configured as an outer liquid guiding cylinder 11B wrapped around the outer side of the inner liquid guiding cylinder 11A. The circumference of the outer liquid guiding cylinder 11B is greater than the circumference of the inner liquid guiding cylinder 11A. When the two ends of the at least two liquid guiding layers 11 are flush, in the unfolded state, a rolled gap 12 is formed between the inner liquid guiding layer 11a and the outer liquid guiding layer 11b. In the rolled state, the inner liquid guiding cylinder 11A and the outer liquid guiding cylinder 11B are in contact.

[0051] The liquid guiding component 10 provided in this application has its outer liquid guiding layer 11b longer than the inner liquid guiding layer 11a along its circumference. This allows a curling gap 12 to be formed between the inner and outer liquid guiding layers 11a before the liquid guiding component 10 is curled (i.e., in its unfolded state). This curling gap 12 provides deformation space for the inner and outer liquid guiding layers 11a and 11b during curling, thereby reducing the compressive force on the inner liquid guiding layer 11a and the tensile force on the outer liquid guiding layer 11b. This reduces the deformation of the flow channels within the inner and outer liquid guiding cylinders 11A and 11B, making the liquid guiding component 10 less prone to leakage or poor liquid guiding.

[0052] Depending on the different dimensions of the inner liquid guiding component 10 of the atomizing core assembly 1 with different structural types, the inner liquid guiding layer 11a and the outer liquid guiding layer 11b can be set to the same thickness or different thicknesses along the radial direction of the inner liquid guiding cylinder 11A and the outer liquid guiding cylinder 11B. This application does not impose any special restrictions on the specific thickness of the inner liquid guiding layer 11a and the outer liquid guiding layer 11b.

[0053] In some embodiments, such as Figure 8 and Figure 9 As shown, at least two liquid guiding layers 11 may further include an intermediate liquid guiding layer 11c disposed between the inner liquid guiding layer 11a and the outer liquid guiding layer 11b; the intermediate liquid guiding layer 11c is configured in a rolled state to wrap around an intermediate liquid guiding cylinder 11C between the inner liquid guiding cylinder 11A and the outer liquid guiding cylinder 11B, with the circumference of the inner liquid guiding cylinder 11A, the intermediate liquid guiding cylinder 11C, and the outer liquid guiding cylinder 11B increasing sequentially; wherein, in the unfolded state, the intermediate liquid guiding layer 11c forms a rolled gap 12 between itself and the inner liquid guiding layer 11a and the outer liquid guiding layer 11b respectively, and in the rolled state, the intermediate liquid guiding cylinder 11C is attached to the inner liquid guiding cylinder 11A and the outer liquid guiding cylinder 11B respectively.

[0054] Therefore, the number of layers of the liquid guiding component 10 is not limited to two layers: the inner liquid guiding layer 11a and the outer liquid guiding layer 11b. An intermediate liquid guiding layer 11c can also be provided between the inner liquid guiding layer 11a and the outer liquid guiding layer 11b to increase the adsorption capacity of the liquid guiding component 10 for the aerosol matrix. At the same time, when the two ends of the intermediate liquid guiding layer 11c are flush with the two ends of the inner liquid guiding layer 11a and the outer liquid guiding layer 11b, respectively, the length of the intermediate liquid guiding layer 11c along the curling direction is greater than the length of the inner liquid guiding layer 11a, but less than the length of the outer liquid guiding layer 11b. This allows a curling gap 12 to be formed between the inner liquid guiding layer 11a, the intermediate liquid guiding layer 11c, and the outer liquid guiding layer 11b when the liquid guiding component 10 is in the unfolded state. This reduces the compressive or tensile force experienced by the intermediate liquid guiding layer 11c when it is curled into the intermediate liquid guiding cylinder 11C, thereby reducing the deformation of the flow channel inside the intermediate liquid guiding cylinder 11C.

[0055] In some embodiments, such as Figure 8 and Figure 9 As shown, at least two liquid guiding layers 11 may also include multiple intermediate liquid guiding layers 11c; the circumference of the multiple intermediate liquid guiding cylinders 11C increases sequentially from the inner liquid guiding cylinder 11A to the outer liquid guiding cylinder 11B; in the unfolded state, a curling gap 12 is formed between adjacent intermediate liquid guiding layers 11c, and in the curled state, adjacent intermediate liquid guiding cylinders 11C are bonded together.

[0056] In this way, the liquid guiding component 10 can be provided with four, five, or more liquid guiding layers 11. Typically, the liquid guiding component 10 can be provided with 2-8 liquid guiding layers 11. This application does not impose any special limitation on the specific number of liquid guiding layers 11 in the liquid guiding component 10. When there are more liquid guiding layers 11 in the liquid guiding component 10, the thickness of each liquid guiding layer 11 is also thinner. This can avoid the problem of inner compression and outer stretching caused by the thickness of the liquid guiding layer 11, thereby helping to reduce the deformation of the fluid channel in the liquid guiding layer 11.

[0057] Along the direction of the curling of the liquid guiding layer 11, the length of the multiple liquid guiding layers 11 increases sequentially from the inner liquid guiding layer 11a to the outer liquid guiding layer 11b, so that a curling gap 12 can be formed between adjacent liquid guiding layers 11 to reduce the deformation of the flow channel when the liquid guiding layer 11 is curled, so that the liquid guiding performance of the liquid guiding component 10 after being curled meets the design requirements.

[0058] In some embodiments, such as Figures 6 to 9 As shown, the liquid guiding member 10 may also have a retention portion 13; in the unfolded state, the retention portion 13 is disposed at at least one end of at least one liquid guiding layer 11; in the curled state, the retention portion 13 extends along the side of the outer liquid guiding cylinder 11B away from the inner liquid guiding cylinder 11A.

[0059] Since the liquid guiding component 10 is usually installed inside the atomizing tube 30, the retention part 13 provided on the liquid guiding component 10 allows a part of the liquid guiding component 10 to extend out of the atomizing tube 30 and directly contact the aerosol matrix, thereby enabling the liquid guiding component 10 to quickly absorb the aerosol matrix for heating and atomization by the heating element 20, avoiding the scorching problem caused by insufficient liquid supply to the liquid guiding component 10.

[0060] The liquid guiding layer 11 on the liquid guiding member 10 can extend entirely along the side of the outer liquid guiding cylinder 11B away from the inner liquid guiding cylinder 11A to form the retention portion 13, or it can partially extend along the side of the outer liquid guiding cylinder 11B away from the inner liquid guiding cylinder 11A to form the retention portion 13. For example, the liquid guiding layer 11 at one end of the liquid guiding member 10 can extend out of the atomizing tube 30 to form the retention portion 13, while the liquid guiding layer 11 at the other end can be curled inside the atomizing tube 30. This application does not impose any special restrictions on the specific shape of the retention portion 13.

[0061] In some embodiments, such as Figures 6 to 9 As shown, each liquid guiding layer 11 has a retention portion 13 at both ends; in the unfolded state, the retention portions 13 at both ends of each liquid guiding layer 11 are stacked and fixed to each other; in the curled state, the ends of the retention portions 13 away from the outer liquid guiding cylinder 11B are flush with each other.

[0062] The retention portions 13 at both ends of the multi-layer liquid guiding layer 11 can be fixed to each other by means of hot pressing or adhesive. This application does not impose any special restrictions on the fixing method between the multi-layer retention portions 13. After the two ends are fixed, the multi-layer liquid guiding layer 11 has a binding force on each other. Since the lengths of the multi-layer liquid guiding layer 11 along the curling direction are different and there are curling gaps 12 between the multi-layer liquid guiding layer 11, the multi-layer liquid guiding layer 11 can undergo micro-curling deformation under the action of the binding force, which is beneficial to the subsequent curling processing of the multi-layer liquid guiding layer 11. In addition, the multi-layer liquid guiding layer 11 after the two ends are fixed can also keep the structure of the liquid guiding component 10 from becoming loose. Furthermore, the ends of the retention portions 13 away from the outer liquid guiding cylinder 11B are flush with each other, so that the retention portions 13 on the multi-layer liquid guiding layer 11 are always flush before and after the liquid guiding component 10 is curled, without the need for separate cutting. This can save the cutting and aligning process after the liquid guiding component 10 is assembled, thereby improving the assembly efficiency of the atomizing device.

[0063] In some embodiments, such as Figures 8 to 10 As shown, this application takes a four-layer liquid-conducting layer 11 as an example. The inner liquid-conducting layer 11a is the first layer, the two intermediate liquid-conducting layers 11c are the second and third layers respectively, and the outer liquid-conducting layer 11b is the fourth layer. The length of the liquid-conducting layer 11 increases sequentially from the inner liquid-conducting layer 11a to the outer liquid-conducting layer 11b. The liquid-conducting layer 11 has a length along the curling direction and a thickness along the curled radial direction. Therefore, the lengths of each liquid-conducting layer 11 are as follows:

[0064] L1 = 2πR + 2L0 - S

[0065] L2 = 2π(R + W1) + 2L0 - 2W1 - S

[0066] L3=2π(R+W1+W2)+2L0-2(W1+W2)-S

[0067] L4=2π(R+W1+W2+W3)+2L0-2(W1+W2+W3)-S

[0068] Wherein, L1 is the length of the first liquid guiding layer 11, L2 is the length of the second liquid guiding layer 11, L3 is the length of the third liquid guiding layer 11, L4 is the length of the fourth liquid guiding layer 11, W1 is the thickness of the first liquid guiding layer 11, W2 is the thickness of the second liquid guiding layer 11, W3 is the thickness of the third liquid guiding layer 11, W4 is the thickness of the fourth liquid guiding layer 11, R is the inner diameter radius of the inner liquid guiding cylinder 11A, L0 is the length of the retention part 13, and S is the distance between the retention parts 13 at both ends of the liquid guiding layer 11.

[0069] Based on the calculation formulas for L1, L2, L3, and L4 above, the increased length ΔL between adjacent liquid-conducting layers 11 is:

[0070] △L=L n+1 -L n =2(π-1)W n ;

[0071] Where n is a positive integer, L n W is the length of the nth liquid-conducting layer 11. n The thickness of the nth liquid-conducting layer 11 is given.

[0072] On the one hand, if the increased length ΔL of the liquid-conducting layer 11 is too long, adjacent liquid-conducting layers 11 may not adhere properly after rolling. On the other hand, if the increased length ΔL of the liquid-conducting layer 11 is too short, adjacent liquid-conducting layers 11 may still have compressive or tensile forces after rolling. This application calculates the increased length ΔL of the liquid-conducting layer 11 to ensure that the length of the liquid-conducting layer 11 is neither too long nor too short. When the increased length ΔL between adjacent liquid-conducting layers 11 satisfies 2(π-1)W n When the liquid guiding layer 11 is rolled up, it can be bent according to its own position, so that the liquid guiding layer 11 can fit together after being rolled up, and the deformation of the flow channel in each liquid guiding layer 11 is minimized.

[0073] In some embodiments, such as Figure 10 As shown, the thickness of each liquid-conducting layer 11 can be the same.

[0074] Thus, according to the above formula, the increase in length ΔL between adjacent liquid-conducting layers 11 is positively correlated with the thickness of the liquid-conducting layer 11. When the thickness of each liquid-conducting layer 11 is the same, the increase in length ΔL between adjacent liquid-conducting layers 11 is a fixed value. That is, the lengths of multiple liquid-conducting layers 11 can be cut in an arithmetic sequence, thereby helping to improve the material feeding efficiency of the liquid-conducting component 10. Of course, in other embodiments, the thicknesses of different liquid-conducting layers 11 may also be different; this application does not impose any special restrictions on the specific thickness of the liquid-conducting layer 11.

[0075] In some embodiments, the liquid guiding layer 11 is made of a flexible porous material.

[0076] Flexible porous materials are not only easy to roll up, but also enable the liquid guiding component 10 to have a strong adsorption effect on the aerosol matrix. For example, the liquid guiding layer 11 can be made of flexible porous materials such as non-woven fabric or absorbent cotton. This application does not impose any special restrictions on the specific material of the liquid guiding layer 11.

[0077] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
